'Raybauld' family name, Ennis query

Re: 'Raybauld' family name, Ennis query

I have found a large amount of information on the family line since locating the census record.

Thus far spellings of the name I have found are:

ReyballReybaldRibaldReybalReballReybauldRhebaldGreybald

However - I have hit a wall. I have located members of the family living in both Ennis and Limerick in the early 1800s. However, I am struggling to find records of the birth of William Reybauld (approx 1815-1825) or his marriage to Catherine Darcy (approx 1840).

I wish to discover William's parents' names, as I believe he may be the key to linking the Reybaulds to the Riboldi family of Limerick.
